Tr) all 't0/tom it may concern." l

Be it known that l, Jox-ix Fot'x'ratx, Jr., a citizen ot' the l'nltedStates, residing at circuits from the wires inclosed iu the pipeElizabeth` in the county of Union and State f Al (l especially designedl'or the purpose.

ot New Jersey. have invented certain new and useful Improvements 1ntou'tbtnation Pull Sleeves, lipe o'r Cable Suppoits or Connectors; and ldo hereby declare the following to be a full, clear` and exact descrip#tion of my invention, such as will enable others skilled in the artA towhich it appe'rtions to make, construct, and use the same.

l'or lighting or power purposes, it is becomingl the universal custom,to provide heavy trunk cables. running usually from `the bot'- tom ot'the building to the top. such cables being ordinarilyv located in theelevator shaft. or in some cases, in a separate shaft, The great lengthol` such cables, coupled with their enormous size and their weight. makeit necessary that they should be supported from the walls ot` thc shaftin which they are located atv frequent intervalsiu order to preservesuch cables from abrasion. due

or conduit, and l Find it convenient to provide one side of 'the devicewith'an opening provided with a removable cover, as hereinafter fullydescribed.

My invention has for its purpose, the provision of suitable means foraccomplishing these and other objects, which will be fully set out inthe following specification.

In the accompanying drawings, Figure l illustrates a front plan ot' myimprovements in position for'supporting A the cable. Fig. lu electricalwiring of large builtlings,

Fig. ois-a t'rout plan,I and Fig. t) is a top plan ot' a gang otl supportsintegrally connected toto their swaying and also to assist in supportingthe sante. to prevent their parting'. gain, it frequently occurs in thewiring' of such buildittgs. that long st retches oi' Wire are requiredto run horizontally through protecting tubes; located in or against thet wallsof the building for the purpose. such t tubes beingl locatedbefore the wiring' is:y

done. Undersuch circumstances, it is a ditlicult. matter to carry thewire through such long stretches ot tube and l make use of the structurehereinafter described. as what hascome to be known 1n the art as a "pullt sleeve7 and pipe connector. the device beine` located in the junctionof two stretches otl pipe, which pipe for the purpose has been cut 'intoshorter lengths than the entire length.I In this manner, the wire orcable may be inserted in one end of the tube and carried t0 the nextjunction where it may be grasped and pulled through and then insertedinto the next succeeding stretch of pipe and carried therethrough. andso on unt-il the entire wiring is thuscompletcd. 'lo close the gapsbetween the adjacent endsI of such pipe, I may use the device, couplingthe same to the cuds otthefpipe, so as to make the same practicallyctitinuous.

In some cases, it is required to lead olf the inclosintg pipe, and 3,gcthetz Fig. l0 isa t'ront plan, and Fig. ll is a top plan illustratinga modified form otl attaching' means. Figs. 1Q andl 13 also illustrate afurther modified forni of attaching means. lfic. l-l illustrates the apY plication of my improvement as a pull sleeve in a horizontal stretchot' cable or wire. and Fig. l5 is a longitudinal section of the same.

Similar numerals ot' reference roter to like parts throughout thespecitication and drawings.

The National Board otl Fire Underwriters require that all electriccables shall bc suitably protected by inclosing them in tubes, as wellas supportingi said cables at intervals. where such cables are suspendedvertically.

In Fig. l, l show a platt \iew ot' mv in vention, in which l representsthe callc, 2

` the coupling or support. This coupling or support is composed'of thetwo sections t and 5. provided withthe enlarged end thitnblcs t and T.The two sections are also provided with laterally projecting aperturedlugs o', with the screw bolts t) for securing the two sections t and 3together. \\'l1en so coupled together the two partsr form a tubularstructure. with the central aperture extending longitudinally throughthe salue. .The enlarged end thine bles 6 and 7 have enlarged internaldiameters ll for the reception of the adjacent ends of the pipe sections2, as shown.

ltlt) pri the walls of said recess, under which conditions it will beforced into the recess byv heavy pressuren rlhe part 1l located in therecess is capable of adJustment and may slide in and out of the recess,beinp' guided by thc two guide screws 16, and helc in xed adjustment bymeans of the bolt 1'? screwed to the outer wall of the recess, andiinpinging upon the back of the friction material liii'lien in use, thecable 1 is strun through the series of pipes 2, which'are of sul'licicntlength to comply with the requirements of each case, with a pair of thesections l and 5 located. between adjacent ends of such tube, as shown,and when in such position, the clamping of the friction material 13 and1A by means of the screw bolt 17 will serve to relieve the cable ofexcessive strain, while at the saine time the thiinbles and "l serve asconvenient coupling means for connecting the adjacent ends of theprotcctive pipe together. Unde` sonic conditions, it is unnecessary togive the coupling any additional support than that. afforded by themetal pipes 2, -which standing vertical and resting upon some suitablesupport in the lower part of thc building, are held from lateralmovement by a series of staples (not shown), at suitable intervals.

Where it desired to afford support for cables which pass directlythrough the .floors of the building, l may provide the thiinbles t3 and7 with the flanges 18 resting directly upon such fio'or and boltedthereto as shown. 'lhe other parts, however, of the coupling will besubstantially the same as illustrated in Figs. 1, 2 and fis illustratedin lligu 3, the ends of the pipe 2 are simply inserted in the enlargedthnnblcs t5 and t and held in position by incansof the grip of the twosections upon the ends of such pipes, which is produced by screwing thesections and 5 together by the bolts t). ,iloweven if desired, thethimbles 6 and '7 on each end of the castings, may be and the endsthreaded asat 29, 'lhe ends of the pipe '2 may be also aded an'l saidpipe and the ends ofthe coupled together by meansv of a i ni aple 3o, asis usually the custom 1n conadacent ends of )i c. l c3 is n'loditiedmeans for supporting'the cable within the coupling, il ma provide the ltconical thimble 3 9, clearly shown in ig., Y, suoli thnnble surroundingthe cable 1, with its exterior conical surface bearing upon theshoulders 2O upon the interior of the enlarged coupling. tendency of thecable 1 will. be arrestedby the more firmly clamping together of thelsplit thimble 19 upon its outer surface.

1t frequently happens that electrical cables are assembled in gangs asillustrated in Fig. Under these conditions, ll may provide the twosections 21 and such sections having the series of internal apertures asillustrated. The series of pipes 2 are held in position by clamping thesame between the two sections 21 and 22, with the cables 1 inside thesame. Either the supporting means comprising the friction materialillustrated in Fig. 3, or the split thinible 19 of Fig. 7 may be used inthe gang coupling illustrated in ligs. 8 and '9, l'f desired, the legs23 may be cast upon one of the sections as 21, `as a means for securingthe same to the side wall of the shaft in which the cables are located.

'lf desired, the section 5 as illustrated in Fig. 2, may be providedwith the feet V211 as wall, or under some circumstances, where thesupport or .coupling comes adjacent to the top of a wall or beam, asingle leg 25, as illustrated in Fig. 12 may be used.

l do not limit myself to the exact means of supporting the coupling fromany adjacent lined structure, and ot-l'ier forms of support will occurto persons skilled in the art of electric wiring, without furthermention of the same here,

is heretofore set forth, l may use the structure as a pull sleeve,locat-ing'the saine between the adjacent ends of two horizontal thecable ,is carried. ln this case, inasmuch as the tube 2 is otherwisesupported, it is unnecessary to provide any other flanges or feet, asillustrated in Figs. 8 to 13 inclusive, forthe reason that the thimbles6 and 7 are clamped directly to the adjacent ends of the pipe or conduit2. 1n this case also, inasmuch as there is no st ain upon the cable orwire, l may omit the clamping devices, heretofore referred to. i

ln the lastmodilication described, l may also provide' one side of theenlarged portion 26 of the pull sleeve with. an .opening 2'2', using thecover 28 to close such opening when all of the parts are secured inposition. 'ln this case, if it becomes necessary to lead out lateralcircuits from the main wire or cable 1, this may be readily done byremoving thc cover 28 and permitting such late al circuits to lead fromthe main wire or cable 1 through the opening 27. Any suitable electriciixture may be substituted vfor the cover 28.
